DESCRIPTION
Refer to speci ¿ c data sheets for À ow capacities and vacuum capacities.
N OTE: Refer to diagrams in this manual for proper rotation and orientation in inlet and discharge.
Tuthill Vacuum & Blower Systems CP Series model rotary lobe blowers are positive displacement type units, whose pumping capacity is determined by size, operating speed, and differential pressure conditions. Blowers employ rotors rotating in opposite directions within a housing closed at the ends by end plates.
The inlet to the discharge is sealed with operating clearances that are very small. Internal lubrication is not needed, as there is no moving contact.
Clearances between the rotors during rotation are maintained by a pair of accurately machined helical timing gears, mounted on the two shafts extended outside the air chamber. The intermeshing rotary lobes are designed to rotate and trap air or gas between each rotor and the housing. As the rotor lobes rotate past the edge of the suction port, the trapped air or gas is essentially at suction pressure and temperature. Since the blower is a constant volume device, the trapped air remains at suction pressure until the leading rotor lobe opens into the discharge port. The close clearances between the rotors inhibit back slippage of the trapped volume from between the rotors, and the trapped volume is forced into the discharge piping. Compression occurs not internal to the blower but by the amount of restriction, either downstream of the blower discharge port or upstream of the blower inlet port.
6
Figure 4-1 illustrates the air movement within the machine. In addition, the machine can operate in either direction.
Never attempt to control capacity by means of a throttle valve in the intake or discharge piping.
This will increase the power load on the drive system, will increase operating temperatures, and can overload and/or seriously damage the blower.
Likewise, if the possibility exists that À ow to the blower inlet may be cut off during normal operation of a process, install an adequate vacuum relief valve. A pressure-type relief valve in the discharge line near the blower is also recommended for protection against cutoff or blocking in this line.
Use check valves on each blower when more than one blower is connected to a discharge line.
When a belt drive is used, it is possible to adjust blower speed to obtain the desired capacity by changing the diameter of one or both sheaves, or by using a variable-speed motor pulley. In a direct-coupled arrangement, a variable-speed motor or transmission is required. Gas blowers can use bypasses, but some applications may require additional cooling. If there is a large volume of high-pressure air or gas downstream of the blower, a check valve in the piping downstream of the blower will protect the blower from overspeeding in a backward direction upon shutdown.
Consult a Tuthill Vacuum & Blower Systems sales professional if questions arise.

Description
!
WARNING
The maximum pressure differential is based on the difference between the inlet pressure and the outlet pressure. The maximum pressure differential shall not be exceeded.
Exceeding the maximum pressure differential will cause serious damage to the equipment and could cause bodily injury.
!
WARNING
The maximum allowable working pressure
(MAWP) is based on the absolute pressure of the blower housing and is NOT the maximum allowable pressure differential. Exceeding the MAWP will cause serious damage to the equipment and could cause bodily injury.
To permit continued satisfactory performance, a blower must be operated within certain approved limiting conditions. The manufacturer’s warranty is, of course, also contingent on such operation.
Maximum limits for pressure, temperature, and speed are speci ¿ ed in Table 4-2 on page 9 for various blower sizes when operated under the standard atmospheric conditions. Do not exceed any of these limits.
Specially ordered blowers with nonstandard construction, or with rotor end clearances greater than shown in Assembly Clearances
on page 40, will not have the operating limits speci ¿ ed here. Contact your
Tuthill Vacuum & Blower Systems sales representative for speci ¿ c information.
Special attention must be paid when a blower has a higher than standard ambient suction temperature. Special recommendations for operating parameters and/or additional cooling may be recommended. Consult the factory or local representative for appropriate information.
10 Manual 2017 Rev C p/n 2017
GENERAL
!
DANGER
The blower is not intended to be used with explosive products or in explosive environments. The blower is not intended to be used in applications that include hazardous and toxic gases. Consult the factory for support.
!
DANGER
It is the responsibility of the installer to assure that proper guarding is in place and compliant with all applicable regulatory requirements.
!
WARNING
The bare shaft blower can generate excessive noise.
Methods to reduce the noise levels by installing inlet and outlet silencers will be required.
Even with inlet and outlet silencers, hearing protection will be required.
05
INSTALLATION
!
WARNING
Customers are warned to provide adequate protection, warning and safety equipment necessary to protect personnel against hazards in the installation and operation of this equipment in the system or facility.
!
WARNING
The standard MAWP is per Table 4-2. The
MAWP shall not be exceeded unless speci
¿
c factory testing of the pressure containing components of the blower has been performed.
!
WARNING
Table 4-2 states the maximum operating speed in RPM (rotations per minute) and maximum temperature. Do not exceed these limits. The installation of the blower shall take these critical operating parameters into account and adequate control features implemented.
11 Manual 2017 Rev C p/n 2017

Installation
!
WARNING
Upon completion of the installation, and before applying power, rotate the drive shaft by hand. It must move freely. If it does not, look for uneven mounting, piping strain, excessive belt tension or coupling misalignment or any other cause of binding.
If blower is removed and still does not move freely, check inside the blower housing for foreign material.
Remove the protective covers from the shaft and inspect for damage.
Carefully check to ensure that no transit damage has been sustained. If damage has occurred from shipment, ¿ le a claim with the carrier immediately.
Preserve the shipping container for inspection by the carrier.
In the event that your unit sustains damage while being shipped to your facility, do not return it to the factory without ¿ rst obtaining shipping instructions from us.
Do not remove protective covers and plugs until the connections are complete. Mount the blower on a À at, level surface. Use a baseplate that is rigid, solidly supported, and structurally sound. Shim under the legs where necessary so that each leg of the blower supports an equal share of the blower weight. This is necessary to prevent twisting of the blower. Make sure the feet rest evenly on the mounting surface before fastening down. Twisting or cramping the blower during mounting will cause rotor contact and binding during operation, resulting in a condition called “soft foot.” See
Soft Foot on page 14 for further details and preventative measures.
A blower that is factory-mounted on a base should not require such adjustments. However, since the assembly can become twisted in shipping or installation, check for soft foot after installing the
12 base. Shims may be needed for alignment. Loosen the foot hold-down screws to check foot contact with the mounting surface. Mount the base on a solid foundation or heavy À ooring, using shims as necessary at bolting points to prevent warping the assembly.
Transmission of small operating vibrations to a support structure may be objectionable in some applications. Use of vibration isolators or vibrationabsorbing materials can be effective in overcoming this transmission. To avoid causing distortion, apply the treatment under the common motor/blower base or mounting plate rather than directly under the feet alone.
Make sure piping is accurately squared with the blower and supported independently. Stress imparted from incorrectly aligned piping or mounting will create problems with bearing and seal life, possibly leading to premature internal contact. The blower should sit stress free and evenly on its supporting surface. Take care to evenly tighten the mounting bolts to avoid imparting undue stress into the blower. Stress can be checked in a free state with feeler stock or veri ¿ ed on a previously installed blower with the aid of a dial indicator. Spring or gap should be less than 0.002 in. (0.05 mm).
Use only clean, new pipe and make certain it is free of scale, cuttings, weld beads, dirt, or any other foreign material. To guard against damage to the blower, make sure that an inlet ¿ lter is used.
Clean the ¿ lter of collected debris after 3 hours of operation and periodically thereafter. See Piping
Connections on page 18 for additional details.
Figure 5-1 shows a typical complete installation of the blower and accessories. Note the absence of throttle or shut-off valves in both discharge and intake piping. If it is possible for air À ow to be cut off in either line, add a pressure and/or vacuum relief valve. In some installations, it may be desirable to use only an inlet silencer-cleaner supported directly from the blower connection. Keep the weight of accessories and piping to a minimum to prevent blower casing distortion. If the weight exceeds
10% of blower weight, support the components independently of the blower and connect them with a
À exible hose or connectors. The approximate weight of the blower is listed in Table 4-1 on page 8 .

Figure 5-1 – Typical Blower Installation
A blower may be driven by direct-coupling to the driver or by V-belt drive for the purpose of obtaining other speeds within the approved range. See Motor Drives on page 19 for more information.
Blowers from Tuthill Vacuum & Blower Systems are internally and externally treated after factory assembly and testing to protect against rusting in normal atmospheric conditions prior to installation.
The maximum period of internal protection is considered to be 6 months under average conditions, provided closing plugs and seals are not removed. Protection against chemical or saltwater atmosphere is not provided. Avoid opening the blower until ready to begin installation, as protection will be quickly lost due to evaporation.
For recommended preparations for long-term storage (longer than 6 months), see Long-Term
Storage on page 29 .

Installation
Location
Install the blower in a room or outdoor area that supplies adequate space and lighting for routine maintenance. Make sure that indoor installation areas are well ventilated and kept as cool as possible, because operating the blower at elevated temperatures can result in nuisance overload or temperature shutdowns. An unprotected outdoor installation is satisfactory only when correct lubrication for the expected temperatures is provided, as per Recommended Lubricants on page 42 .
Foundation
The blower does not need a special foundation.
However, it does require a solid, level À oor and adequate frame support. Bolt the blower system to the À oor and seal any cracks.
Blower Air Intake
To minimize maintenance, supply the blower with the cleanest air possible. The air must not contain any À ammable or toxic gases, as the blower will concentrate these gases. This could result in damage to the blower and surrounding property and lead to personal injury or death. Do not block or restrict the opening of the blower, as the motor could overheat and fail.
Do not use blowers on explosive or hazardous gases. Do not exceed the limits described in Table
4-2 on page 9 on performance criteria such as pressure differential, running speed, and discharge temperature.
If it is necessary to take air from a remote source, such as in a vacuum application, make sure the diameter of the piping is at least equal to the diameter of the blower inlet. For distances greater than 20 ft (6 m), enlarge the pipe diameter to reduce inlet restriction. Excessive restriction will reduce the ef ¿ ciency of the blower and elevate its discharge temperature. The piping used should also be corrosion-resistant and free of scale and dirt. Keep the inlet covered to keep out foreign objects and rain. Vacuum kits are available.

Installation
Soft Foot
Soft foot is a condition in which one of the blower feet does not sit À at on the base. Soft foot is usually due to irregularities in the surface to which the blower is mounted. When the bolt on the foot gets tightened, a slight distortion occurs that can affect bearing and seal life as well as internal contact between parts.
ANGULAR
SOFT FOOT
SAFETY
Tuthill Vacuum & Blower Systems recommends the use of relief valves to protect against excessive pressure or vacuum conditions. Test these valves at initial start-up to be sure they are properly adjusted to relieve at or below the maximum pressure differential rating of the blower.
!
DANGER
It is the responsibility of the installer to assure that proper guarding is in place and compliant with all applicable regulatory requirements.
PARALLEL
SOFT FOOT
Figure 5-2 – Illustrations of Soft Foot
1. Place the blower on the base.
2. Check each foot for gaps between the foot and base (soft foot). Shim as necessary to ¿ ll the gap within 0.002 in. (0.05 mm).
Figure 5-2 shows the two most common types of soft foot conditions. If either type is present at a measurement of more than 0.003 in.
(0.076 mm), the blower may fail prematurely.
3. Tighten all bolts.
4. Mount a dial indicator on the base contacting one foot at 12 o’clock position.
5. Loosen the bolt on that foot. Observe indicator travel and add shims as needed to reduce
“spring” to less than 0.002 in. (0.05 mm).
Repeat steps 4 and 5 on the remaining feet.
!
DANGER
Internal and external rotating parts of the blower and driving equipment can produce serious physical injuries. The blower should never be run with the inlet or discharge piping removed. If it becomes necessary to inspect the rotating parts of the blower or to change V-belts, be absolutely sure that all power to the motor controls has been shut off, the motor controls are locked out, and properly tagged before proceeding.

LUBRICATION
Every blower from Tuthill Vacuum & Blower
Systems is factory-tested, oil-drained, and shipped dry to its installation point. Fill both independent oil reservoirs to the proper level before operation.
Shaft bearings at the gear end of the blower are splash-lubricated by one or both gears dipping into an oil reservoir formed in the gear end plate and cover. Shaft bearings at the drive end of the blower are lubricated by a slinger assembly dipping into an oil reservoir. Before starting the blower, ¿ ll the oil sumps as described in Filling Procedure on page 16 .
Add oil to the blower in the quantity listed in Table 4-1 on page 8 . Make sure oil level is maintained within the notched area of the sight glass. See Figure 5-3 . Lower drive blowers have
“bull’s eye” type oil level gauges. Maintain oil levels at the center of the glass.
!
WARNING
Never attempt to change or add lubrication while the blower is running. Failure to heed this warning could result in damage to the equipment or personal injury. Oil must be checked when the blower is NOT running.
!
WARNING
Properly dispose of the spent lubricants.
Refer to the manufacturer of the lubricant and any regulations to assure proper and safe disposal.
!
WARNING
Do not start the blower until you are sure oil has been put in the gear housing and rear cover. Operation of the blower without proper lubrication will cause the blower to fail and void the warranty.

Frequently Asked Questions Regarding
Lubrication
What is the functional detriment if the “wrong oil” is used?
The lubricant is selected based on bearing speed, gear speed, and operating temperature.
If the lubricant is too light, it increases wear by not separating the sliding surfaces and it will not remove the heat adequately. If the lubricant is too thick, the drag in the bearings is increased, causing them to run hotter. Thicker lubricant will not À ow as readily into the gears and it will reduce the available backlash. Lubricants at our conditions are incompressible.
What is the functional detriment if the oil is not serviced?
If the lubricant is not serviced at the proper interval, the shearing action in the bearing and the gears will begin to take its toll and the lubricant will thicken. The blower will run hotter and the wear on moving parts will increase. The lubricant will generally appear dirtier, caused by material rubbing off the components. The lubricant will discolor because of overheating. An indicator of the breakdown of a lubricant is the increase in the Total
Acid Number (TAN) and a change of 10 percent in the base viscosity.
Several things are happening as the lubricant goes through the blower. First, it is absorbing frictional energy in the form of heat. This heat has to be dissipated through either surface contact with cooler materials or in a rest volume of lubricant. While reducing the friction, the lubricant is also going through a shearing process and the molecular structure is broken down.
The result is that the lubricant will begin to thicken because of the shorter molecular chains and the drop out of additive packages. The thickened lubricant will cause more drag, increasing the friction and heat and further degrading the lubricant.
Operation of the blower (environment, run time, speed, and pressure) has a direct effect on duty cycles. The published cycles are based on worstcase conditions.

PIPING CONNECTIONS
!
WARNING
Pipe loading on the blower should be negligible as pipe loading can cause distortion of the blower. Use proper supports and pipe hangers to assure that there is no loading.
Remove the protective covers from the inlet and outlet ports and inspect for dirt and foreign material.
Inlet and outlet connections on all blowers are large enough to handle maximum volume with minimum friction loss. Maintain same-diameter piping. Do not support silencers by the blower.
Avoid stress loads and bending moments.
Be certain all piping is clean internally before connecting to the blower. Place a 16-mesh wire screen backed with hardware cloth at or near the inlet connections for the ¿ rst 50 hours of use until the system is clean. Clean the screen after
3 hours of operation and completely discard it once the system is clean, as it will eventually deteriorate and small pieces going into the blower can cause serious damage. A horizontal or vertical air À ow piping con ¿ guration is easily achieved by rearranging the mounting feet position.
Hazards Associated With Hazardous
Process Fluids
!
DANGER
It shall be the responsibility of the installer to ensure that piping is adequate, sealing between pipe joints is adequate for the process
À
uids and proper process and pressure protection devices are in place.
It is also the responsibility of the installer to assure that process gases are not vented in a manner that would be hazardous.
Refer to the manufacturer of the process media to assure that proper safety precautions are in place.
Blockage or Restriction
!
WARNING
Damage to the blower could occur if there is blockage in the inlet or outlet ports or piping.
Care should be taken when installing the blower to assure that there are no foreign objects or restrictions in the ports or piping.
18 Manual 2017 Rev C p/n 2017
MOTOR DRIVES
Two drive connections commonly used are direct drive and V-belt drive.
Direct Coupled
When installing the motor directly to the blower, align the shafts to the coupling according to the coupling manufacturer’s instructions. Blowers shipped with the motor directly coupled and mounted on a common base have been aligned prior to shipment. Further alignment is not normally necessary, but be sure to check the alignment and make adjustments if necessary prior to starting the blower.
Coupling halves must correctly ¿ t the blower and drive shafts so that only light tapping is required to install each half. The two shafts must be accurately aligned. A direct-coupled blower and motor must be aligned with the two shafts having no more than
0.005 in. (13 mm) Total Indicator Reading (TIR).
Make sure the face is aligned within 0.002 in.
(0.05 mm).
Establish proper gap between coupling halves according to the coupling manufacturer’s instructions with the motor armature. Proper gap will minimize the chance for end thrust on the blower shaft. Re-align and grease all direct-coupled base-mounted blowers after ¿ eld installation.
V-Belts
If the motor and blower are V-belt connected, the sheaves on both the motor and blower shafts should be as close to the shaft bearings as possible. Blower sheave is not more than 1/4 in.
(6.5 mm) from the blower drive end cover. The drive sheave is as close to the driver bearing as possible. Take care when installing sheaves on the blower and motor shafts. Make sure the face is accurately in line to minimize belt wear.
05
Installation
Adjust the belt tension to the manufacturer’s speci ¿ cations using a belt tension tester. Check new belts for proper tension after 24 hours of run time. When manufacturer data is not available, industry guidelines recommend 1/64 in. de À ection for each inch of span (0.157 mm de À ection per centimeter of span) at 8 – 10 lb (3.6 – 4.5 kg) of force in the center of the belt.
Insuf ¿ cient tensioning is often indicated by slipping
(squealing) at start-up. Do not use belt dressing on V-belts. Keep sheaves and V-belts free of oil and grease. Remove tension from belts if the drive is to be inactive for an extended period of time. For more speci ¿ c information, consult the drive manufacturer. In a V-belt drive, the blower sheave must ¿ t its shaft accurately, run true, and be mounted as close to the bearing housing as possible to minimize bearing loads.
A tight or driving ¿ t will force the drive shaft out of its normal position and cause internal damage. A loose ¿ t will result in shaft damage or breaking.
Make sure the motor sheave ¿ ts correctly and is properly aligned with the blower sheave.
Adjust the motor position on its sliding base so that belt tension is in accordance with drive manufacturer’s instructions. Always avoid excessive belt tension. Recheck tension after the ¿ rst 10 hours of operation and periodically thereafter to avoid slippage and loss of blower speed.
Check the blower after installation and before applying power by rotating the drive shaft by hand.
If the drive shaft does not rotate freely:
• Look for uneven mounting, piping strain, excessive belt tension, or coupling misalignment
• Check the blower to make sure oil was added to the reservoirs

Figure 5-5 – Setting of proper tension for a V-belt drive
Factors outside the control of the belt tensioning system used on an individual blower package assembly, such as environmental factors and quality of the belts installed, may contribute to decreased belt life. Such factors can cause wear of the belts beyond the ability of the tensioning system to compensate.
As such, it is recommended to check belt tension monthly and make any manual adjustments found necessary.
1. Turn off and lock out power.
2. Remove the belt guard fasteners (if equipped).
3. Remove the belt guard.
4. Check and adjust the belt tension as necessary. Tension should be 1/64 in. de À ection per inch of span (0.157 mm de À ection per centimeter of span) between sheaves, with 8 – 10 lb (3.6 – 4.5 kg) force applied at the center point of the top section of belt.
5. Install the belt guard, making sure that all drive components are free of contact with the guard.
6. Install the belt guard fasteners that were removed in step 2.
7. Unlock the power and start the blower.
8. Resume normal operation.

WARNING
The blower can generate excessive noise. Hearing protection is required while the unit is in operation.
Before starting the blower for the ¿ rst time under power, recheck the installation thoroughly to reduce the likelihood of dif ¿ culties. Use the following checklist as a guide, but consider any other special conditions in your installation.
1. Be certain no bolts, rags, or dirt have been left in blower.
2. Be certain that inlet piping is free of debris. If an open outdoor air intake is used, be sure the opening is clean and protected by an inlet ¿ lter.
This also applies to indoor use.
3. If installation is not recent, check blower leveling, drive alignment, belt tension, and tightness of all mounting bolts.
4. Be certain the proper volume of oil is in the oil reservoir chambers.
5. Be certain the driving motor is properly lubricated and connected through suitable electrical overload devices.
6. With electrical power off and locked out to prevent accidental starting, rotate the blower shaft several times by hand to make sure the blower is rotating freely. Unevenness or tight spots are indicators of a condition that should be corrected before progressing.

06
Operation
7. Check motor rotation by momentarily pushing the START button and then checking the À ow direction of the blower. Reverse the motor connections if the À ow is in the wrong direction.
Carry out initial operation under “no load” conditions by opening all valves and venting the discharge to the atmosphere, if possible. Then, start the motor brie À y, listen for unusual noises, and make sure the blower coasts freely to a stop.
If no problem appears, repeat this check and let the motor run slightly longer. If any questions exist, investigate before proceeding.
Assuming all tests are satisfactory, the blower will now be ready for continuous full-load operation.
During the ¿ rst several days, check periodically to make sure all conditions remain acceptable and steady. These checks may be particularly important if the blower is part of a process system where conditions may vary. At the ¿ rst opportunity, stop the blower and clean or remove the inlet ¿ lter.
Also recheck leveling, coupling alignment or belt tension, and mounting bolts for tightness.

Operation
RECOMMENDED SHUTDOWN
PROCEDURE TO MINIMIZE RISK OF
FREEZING OR CORROSION
When an air piping system has high humidity or moisture, water condensation can occur after the blower is shut down and it begins to cool.
Condensation creates an environment favorable to corrosion of the iron internal surfaces and to ice formation in cold weather. Both conditions can close the operating clearances, causing the blower to fail upon future start-up.
The following shutdown procedure minimizes the risk of moisture condensation, corrosion, and freezing.
4. If the blower is being taken out of commission for an extended period of time, see Long-
Term Storage on page 29 .
Care must be taken not to overload or overheat the blower during this procedure.
1. Isolate the blower from the moist system piping, allowing the blower to intake atmospheric air. Operate the blower under a slight load, allowing the blower to heat within safe limits. The heat generated by the blower will quickly evaporate residual moisture.
2. For carpet cleaning applications, after the work is completed, allow the blower to run
3 – 5 minutes with the suction hose and wand attached. The suction hose and wand will provide enough load to the blower to evaporate the moisture quickly.
3. For extended shutdown, inject a small amount of a light lubricating oil such as 3-in-One® or a spray lubricant such as WD-40® into the inlet of the blower just before shutdown (3-in-
One and WD-40 are registered trademarks of
WD-40 Company) . The lubricant will provide an excellent protective coating on the internal surfaces. If using a spray lubricant, take care to prevent the applicator tube from getting sucked into the blower. The applicator tube will damage the blower, likely to a degree where repair would be required.

MAINTENANCE
GENERAL
Regular inspection of the blower and its installation, along with complete checks on operating conditions, will pay dividends in added life and usefulness. Also, service the drive per the manufacturer’s instructions and lubricate the coupling or check the belt drive tension. Use thermometers and gauges to make sure that blower operating temperature and pressure remain within allowed limits.
!
DANGER
The blower and parts may contain hazardous media.
Assure that pump and parts are evacuated of hazardous media prior to servicing.
!
CAUTION
The electrical service must be isolated and de-energized prior to maintenance. Apply appropriate procedures to assure electrical supply is de-energized and cannot be inadvertently energized during maintenance.
Assure piping and product is isolated prior to maintenance of blower. Apply appropriate procedures to assure piping and product is isolated and that inadvertent opening of valves cannot occur during maintenance.
Manual 2017 Rev C p/n 2017
!
CAUTION
During routine maintenance, inspect and assure that guards are in place and secure.
Pay special attention to lubrication of timing gears and bearings according to the information in
Lubrication on page 15 .
When a blower is taken out of service, it may require internal protection against rusting or corrosion. The need for such protection must be a matter of judgment based on existing conditions as well as length of downtime. Under atmospheric conditions producing rapid corrosion, protect the blower immediately. See Long-Term Storage on page 29 .
REGULAR MAINTENANCE
A well-designed maintenance program will add years of service to the blower.
Check a newly installed blower frequently during the ¿ rst month of operation, especially lubrication.
With the blower at rest, check the oil level in both the gear (drive) end and free (non-drive) end of the blower and add oil as needed. Complete oil changes are recommended every 1,000 – 1,200 operating hours, or more frequently depending on the type of oil and operating temperature. Also change the oil more frequently if pumping corrosive vapors or where excessive operating temperatures are encountered. The following is recommended as a minimum maintenance program.

Maintenance
DAILY WEEKLY MONTHLY
1. Check and maintain oil level, and add oil as necessary.
2. Check for unusual noise or vibration ( page 38 ).
see
Troubleshooting on
1. Clean all air ¿ lters. A clogged air ¿ lter can seriously affect the ef ¿ ciency of the blower and cause overheating and oil usage.
1. Inspect the entire system for leaks.
2. Inspect the condition of the oil and change if necessary.
2. Check the relief valve to make sure it is operating properly.
3. Check drive belt tension and tighten if necessary.
Oil levels should be checked every 24 hours of operation.
Proper oil drain schedules require oil be changed before the contaminant load becomes so great that the lubricating function of the oil is impaired or heavy disposition of suspended contaminants occurs. To check the condition of the oil, drain a sample into a clean container and check for the presence of water or solids. Slight discoloration of the oil should not necessitate an oil change.
In developing a stock of spare parts, consider the following factors:
• The degree of importance in maintaining the blower in a “ready” condition
• The time lag in parts procurement
• Cost
• Shelf life (seals and O-rings)
SPARE PARTS
Should adjustments or replacement be needed, repairs can often be performed locally as described in this manual after obtaining the required parts.
Personnel should have a good background of mechanical experience and be thoroughly familiar with the procedures outlined in this manual. For major repairs not covered in this manual, contact the nearest Tuthill Vacuum & Blower Systems service representative.
When ordering parts, supply the blower nameplate information, as well as the item number and parts description as per the parts lists and assembly drawings. Repair kits are available for all models.
These kits contain all the seals, bearings, O-rings, locks, and special retaining screws necessary for an overhaul. For convenience when ordering parts, complete the Operating Data Form included on the inside back cover of this manual.
FACTORY SERVICE AND REPAIR
With proper care, Tuthill Vacuum & Blower
Systems blowers will give years of reliable service.
The parts are machined to close tolerances and require special tools by mechanics who are skilled at this work. Should major repairs become necessary, contact the factory for the location of the nearest service facility. Blowers that are still under warranty must be returned to the factory, freight prepaid, for service.
Current regulations require Material Safety
Data Sheet to be completed and forwarded to
Tuthill Corporation on any unit being returned for any reason which has been handling or involved with hazardous gases or materials.
This is for the protection of the employees of
Tuthill Corporation who are required to perform service on this equipment. Failure to do so will result in service delays.
28 Manual 2017 Rev C p/n 2017
When returning a blower to the factory for repair, under warranty, please note the factory will not accept any unit that arrives without authorization. Contact the Service Department for return authorization.
LONG-TERM STORAGE
Any time the blower will be stored for an extended period of time, make sure it is protected from corrosion by following this procedure:
1. Spray the interior (lobes, housing, and end plates) with rust preventative. Repeat as conditions dictate and on an at least a yearly basis.
2. Fill both end covers completely full of oil.
3. Firmly attach a prominent tag stating that the end covers are full of oil and must be drained and re ¿ lled to proper levels before start-up.
4. Apply a rust-preventative grease to the drive shaft.
5. Spray all exposed surfaces, including the inlet and discharge À anges, with rust preventative.
6. Seal the inlet, discharge, and vent openings.
It is not recommended that the blower be set in place, piped to the system, and allowed to remain idle for a prolonged amount of time. If any component is left open to the atmosphere, the rust preventative will escape and lose its effectiveness.
7. During storage, make sure the blower does not experience excessive vibration.
8. Attach a desiccant bag to one of the covers to prevent condensation from occurring inside the blower. Make sure any desiccant bag (or bags) is attached to the covers so that they will be removed before start-up of the blower.
9. Store the blower in an air conditioned and heated building if possible. If air conditioned and heated storage is not possible, make conditions as dry as possible.

16. Remove the seals from both end plates with a punch or dull chisel. The seals will be damaged during removal and must be replaced. Inspect all parts for wear or damage.
17. Clean and inspect all parts for burrs, and polish the seal journals with at least 320-grit emery or crocus cloth.
REASSEMBLY OF BLOWER
After thoroughly cleaning the seal and bearing bores of both end plates, apply a thin coat of sealant on the outside diameter of the new seals and press them into the end plate using a tool that will bear on the outer edge of the seal. The spring side of the seal should be facing you. Apply a thin coat of grease to the seal lip.
See Special Tool Drawings on page 44 for drawings and dimensions of the seal and bearing pressing tools.
Using the drive end plate as a ¿ xture, support the plate high enough so the input shaft of the drive rotor clears the assembly surface (see Figure
8-10 ). Place the rotors in the ¿ xture with the drive rotor to the left (see Figure 8-10 and Figure 8-14 ).

Disassembly and Reassembly
Adjusting Rotor Interlobe Clearance
1. Use feeler gauges to take interlobe readings, and record them on each side of housing as indicated in Figure 8-15 . As shim is removed or added behind the helical gear, the gear rotates as it is moved in or out and the driven rotor turns with it, thus changing the clearance between rotor lobes.
Figure 8-15 – Checking Rotor Interlobe Clearances
2. Changing the shim thickness will change the rotor lobe clearance. remove, subtract the smaller value from the larger value.
36
EXAMPLE: Referring to Figure 8-15 , check the clearance at AA (right-hand reading) and
BB (left-hand reading). If the AA reading is
0.009 in. (0.23 mm) and the BB reading 0.003 in. (0.08 mm), adjust by removing 0.006 in.
(0.15 mm) shims from the driven rotor. The readings will change one half the amount removed: 0.003 in. (0.08 mm). AA should then read 0.006 in. (0.15 mm) and BB should read
0.006 in. (0.15 mm). The ¿ nal readings should be within 0.002 in. (0.05 mm) of each other.

All accessories furnished by Seller but manufactured by others bear only that manufacturer’s standard warranty.
All claims for defective products, parts, or work under this warranty must be made in writing immediately upon discovery and, in any event within one (1) year from date of shipment of the applicable item and all claims for defective work must be made in writing immediately upon discovery and in any event within one (1) year from date of completion thereof by Seller. Unless done with prior written consent of Seller, any repairs, alterations or disassembly of Seller’s equipment shall void warranty.
